Baddeley (1986, 1992) describes WM as a limited capacity central executive system that interacts with a set of two passive store systems used for temporary storage of different classes of information: the speech-based
articulatory loop, and the visual sketch pad.

Second, it was shown that there was no ISE under conditions of articulatory suppression -- a finding consistent with the hypothesis that lipread items must pass through the
articulatory loop prior to entry to the store.
In order to account for these results, Baddeley & Hitch (1974) and Baddeley (1986) introduced the idea of an
articulatory loop, more recently a phonological loop (Baddeley, 1990), as a part of a broader conceptualization of short-term memory that they called working memory.
According to Eysenck, worry affects tasks which impose demands on the capacity of working memory, mainly via the central executive, and, to a lesser degree, the
articulatory loop. Anxiety affects the performance of such tasks by pre-empting some of the resources available in the working memory system; the more difficult the task, the greater the demands made upon the resources of working memory.
In short-term verbal memory, information about serial order is thought to be maintained by a phonological system and an
articulatory loop. Burgess & Hitch (1992) have pointed out that one of the major functions of this system is the preservation of order, even if accounts of how serial order is maintained in such a system do not explain order errors in verbal recall.
The time limited basis of the
articulatory loop provides a natural explanation for the word length effect (Baddeley, Thomson & Buchanan, 1975); the inverse relationship between span and the articulatory duration of stimuli.
Studies of short-term memory for written or spoken information have suggested that suppression disrupts a temporary phonological store known as the
articulatory loop (Baddeley, 1986; Baddeley & Hitch, 1974).
Verbal speech-based information is dealt with by the
articulatory loop, whilst visuospatial material is manipulated and stored using a specialized system known as the visuospatial scratchpad or sketchpad (VSSP).
The
articulatory loop system is specialized for processing verbal material and is composed of two subsystems: a phonological store and an articulatory rehearsal process.
